Abstract
The present invention has an object to enable to supply a discharged pressurized fluid of a hydraulic pump without any energy loss with an arbitrary flow rate distribution ratio to a plurality of actuators. A discharged pressurized fluid of the hydraulic pump,is supplied to the first and second actuators,and,via the first and second variable displacement type hydraulic pump/motors,and,The first variable displacement type hydraulic pump/motor,and the second variable displacement type hydraulic pump/motor,are mechanically connected to rotate at the same revolution speed. By this, the pressurized fluid is supplied to the first and second actuators,and,depending upon displacements of the first and second variable displacement type hydraulic pump/motors.
